Development and Application of a Technique for Steady State Aerodynamic Heat Transfer Measurements


Hartwig, Frederic William (1957) Development and Application of a Technique for Steady State Aerodynamic Heat Transfer Measurements. Dissertation (Ph.D.), California Institute of Technology. doi:10.7907/Y2JY-A341.


A technique was developed for measuring steady state heat transfer on a hemisphere cylinder and the results are compared with theory. The instrumentation consisted of a miniaturized thermopile of silver-constantan thermocouples approximately 1/8" x 1/16" x 1/100". The repeatability of readings with this device was found to be excellent. These heat measuring devices, or heat meters, were installed in both a ceramic hemisphere cylinder and in a similar metal one. There were obtained three different heat flow rates at each of six different combinations of tunnel pressure and temperature.

The results compared very well with a theory developed by Lester Lees based upon the assumption of local similarity.
